From a news article in euronews:
“The St George church in the Czech village of Lukova, features some unearthly sights.
With the church abandoned after World War 2 when ethnic German parishioners were expelled by the Czechs, art student Jakub Hadrava decided to fill it’s pews with ghostly figures.
The sculptures were created from plaster casts of live models draped in white cloth.” (This article is at http://www.euronews.com/2018/09/06/tourists-interest-piqued-by-czech-ghost-church )
